Answer:
x^2
Step-by-step explanation:

Hope this helps!
Set up two seperate equations
first the volume equation
1728=length*width*height
we know the height is 6ft
1728=L*W*6
divide both sides by 6
288=L*W
then the second equation
L=4.5W
if one side is 4.5 times larger
then take that and plug it back into the first equation
288=(4.5W)*W
288=(4.5)w^2
divide both sides by 4.5
64=w^2
so w=8
then plug that back into the last equation
L=4.5(8)
L=36
Answer:
Step-by-step explanation:
it depends. if (for example) y=x2 then there are an infinite amount of answers. if there is an equation like: If (variable X)= (variable Y) + 5 and if X=5, what is Y? then there is only one answer. check an algebra book, it can give you a more detailed answer.
